Shrinking Fluoropolymer Tubing

Most Fluoropolymers will begin shrinking around 230° F and see full recovery around 300° F, however temperature is not the only factor when shrinking Fluoropolymer Tubing. Time also plays and important role in the shrinking of FEP and PFA Tubing. A long heat soak is also important in making sure that you get full recovery from your tubing.

For applications that are using PTFE Tubing higher temperatures of 620°F are required in order for the material to begin its shrinking process. Even though PTFE Tubing can see higher temperatures than PFA and FEP during the shrinking process too much heat will cause PTFE to split longitudinally and have to be replaced.

With over 50 years of Fluoropolymer experience that stretch back to the emergence of resins such as PTFE, FEP and PFA founder John F. Walls has pushed his employees and propelled his company to become a top competitor in the Fluoroplastic field. From simple extrusions to custom heat shrinkable FEP & PTFE Tef Cap Industries prides itself on not only being a global tubing supplier but also a one stop shop for all your Fluoropolymer secondary processes.
